EFFECTS OF VARIOUS SHAPES OF DOG SPIKES ON THEIR WITHDRAWAL RESISTANCE

One method of improving the holding power of dog spikes is to modify the shape of the spikes. An experiment was undertaken to test the modified spikes. The paper briefly describes the experiment performed. The standard dog spike used by JNR was designated A-type. The other designations represented proposed modifications. The average holding powers of the spikes tested after repeated pulling are as follows; beech blocks--A 2,253, B 2,119, C 2,030, D 2,263, E 2,256, F 2,384 kg. Hinoki blocks--A 2,041, B 1,983, C 2,060, D 2,060, E, 2,048, F 2,244 kg. It can be concluded that the modified spikes proposed are not better than the standard dog spikes specified by the current JNR standard.
